     Driving to a friend's house on a recent evening, I was attracted by the sight of the full moon rising just

above my friend's rooftops. I stopped to watch it for a few moments, thinking about what a pity it was

that most city people, myself included, usually miss sights like this because we spend most of our lives

indoors.

     My friend had also seen it. He grew up living in a forest in Europe, and the moon meant a lot to him

then. It had touched much of his life.

     I know the feeling. Last December I took my seven-year-old daughter to the mountainous jungle of

northern India with some friends. We stayed in a forest rest-house with no electricity or running hot water. Our group had campfires outside every night, and indoors when it was too cold outside. The moon grew

to its fullest during our trip. Between me and the high mountains lay three or four valleys. Not a light shone

in them and not a sound could be heard. It was one of the quietest places I have ever known, a bottomless well of silence. And above me was the full moon, which struck me deeply.   

     Today our lives are filled with glass, metal, plastic and fibre-glass. We have televisions, cell phones,

pagers, electricity, heaters and ovens and air-conditioners, cars, computers.

     Struggling through traffic that evening at the end of a tiring day, most of it spent indoors, I thought:

before long, I would like to live in a small cottage. There I will grow vegetables and read books and walk

in the mountains And perhaps write, but not in anger. I may become an old man there, and wear the

bottoms of my trousers rolled and measure out my life in coffee spoons. But I will be able to walk outside on a cold silent night and touch the moon.
